That's enough for a modest firmware image — a few hundred lines of C with a small state machine, I²C driver, and a UART command parser. It will not run a TCP/IP stack or buffer large ADC logs. Plan firmware around the 2 KB ceiling from day one. ## I/O and connectivity — 24 pins in a 28-TSSOP ## Peripherals — brown-out, PWM, watchdog On-chip peripherals include brown-out detect and reset (BOR), a PWM timer, and a watchdog timer (WDT). The BOR is critical for battery or capacitor-backed supplies — it holds the MCU in reset until the rail is stable, preventing code corruption during brown-out events. The PWM channel can drive a small DC motor or LED dimmer directly, saving an external timer IC. ## Supply and temperature range TI lists the MSP430G2203IPW28R as Active. For dual-source resilience, TI's MSP430G2xx family includes pin-compatible density variants — confirm the exact Flash/RAM match before substituting.","metaTitle":"TI MSP430G2203IPW28R 16-bit MCU, 16 MHz, 2 KB Flash, 28-TSSOP","metaDescription":"MSP430G2203IPW28R from TI: 16-bit MSP430 CPU16 at 16 MHz, 2 KB Flash, 256 B RAM, 24 GPIO, I²C/SPI/UART, -40°C to 85°C, 28-TSSOP.
